Question 11 b)
I don't see why they ignore the white milk in the middle in their model. Nor do I understand how they get that the white milk is also traveling at U. As for the rest of the algebra, there's no need to explain.
Do not understand 11c) statements:
- "Chocolate and plain milk might mix: any mixing will dissipate the kinetic energy of the wave at a microscopic level."
- "The chocolate milk and plain milk will also exert forces on each other. The wave is not made up of two blocks!" - Don't two blocks also exert forces on each other? What difference is the force exerted by these liquids on each other? What force is exerted by these liquids on each other?
Not to sure on the inner mechanics of how gravitational potential energy gets changed into a horizontal kinetic energy (normally its via a ramp). Someone explain please.
Please help.
